Description
■ Removed the MAXADCSPD bit field from the DCGC0 register as it has no function in deep-sleep
mode.
■ Deleted reset value for 16-bit mode from GPTMTAILR, GPTMTAMATCHR, and GPTMTAR registers
because the module resets in 32-bit mode.
■ Clarified CAN bit timing and corrected examples.
■ Clarified PWM source for ADC triggering
■ Made these changes to the Electrical Characteristics chapter:
– Removed V_SIH and V_SIL parameters from Operating Conditions table.
– Changed SSI set up and hold times to be expressed in system clocks, not ns.
– Revised ADC electrical specifications to clarify, including reorganizing and adding new data.
– Changed the name of the t_{HIB_REG_WRITE} parameter to t_{HIB_REG_ACCESS}.
– Table added showing actual PLL frequency depending on input crystal.
■ Additional minor data sheet clarifications and corrections.

■ Clarified Power-on reset and RST pin operation; added new diagrams.
■ Corrected the reset value of the Hibernation Data (HIBDATA) and Hibernation Control (HIBCTL)
registers.
■ Clarified explanation of nonvolatile register programming in Internal Memory chapter.
■ Added explanation of reset value to FMPRE0/1/2/3, FMPPE0/1/2/3, USER_DBG, and USER_REG0/1
registers.
■ Changed buffer type for WAKE pin to TTL.
■ In ADC characteristics table, changed Max value for GAIN parameter from ±1 to ±3 and added
E_IR(Internal voltage reference error) parameter.
■ Changed ordering numbers.
■ Additional minor data sheet clarifications and corrections.

■ Added JTAG/SWD clarification (see “Communication with JTAG/SWD” on page 164).
■ Added clarification that the PLL operates at 400 MHz, but is divided by two prior to the application
of the output divisor.
■ Corrected bits 2:1 in I2CSIMR, I2CSRIS, I2CSMIS, and I2CSICR registers to be reserved bits
(cannot interrupt on start and stop conditions).
■ Corrected bits 15:11 in USBTXMAXP0/1/2 and USBRXMAXP0/1/2 registers to be reserved bits
(cannot define multiplier).
■ Additional minor data sheet clarifications and corrections.
